water heaters and purifiers, and has for its principal objects; the provision of animproved feed water purifier which 1s entirely closed in order to prevent the spilling of the contents thereof; the, provision of an improved feed water heater and purifier composed of sections detachably held together so that the'parts may be readily assembled and put in place, and as readily taken apart for cleaning; the provision of improved means for securing together and supporting the sections of a sectional feed water purifier; and in general the provision of a device of the character specified which is simple in construction and efiective in'opersrtion and aarticularly applicable for use on marine oilers. 'These to ether with sit ch other cojects as may hereiiia terappear or are incidental to my invention, I attain by ineans ofafconstri-lction illustrateddn preferred form in the accompanying drawings, whe eine Figure 1 is a, longitudinal section through a portion of it boiler, showing my improved purifier in section,

Figure 2 is an enlarged plan view of a portion of the purifier,

Figure 3 is an enlarged section on the line III III of Figure Land 7 t Figure 4 is an end View of a, boiler showingt ie location of the various parts.

'eferring to Fi ure 1 of the drawings, it will be seen that I are shown a portion of a boiler 1. having the usual fines or boiler tubes-2 andprovided with the sta bolts or tie rods 33 to support the boiler head 4. Suspended within the boiler shell from two-of the tie-rods 3t "is the feed water heater and purifier which "is "preferably composed-of three cylindrical sections 5, fiend 7- fletachabgr held together in a manner to' be idescribe The seetipnshfi-t into rings or joinin members 8 and 9 and irings' or heads 10 an 11,4111 of which are rovided with a plurality of slots 12 adapts toreeeive the through bolts or rods 18 which alternately extend in opposite directions and serve to hold and bind the sections and rings the one to the other. This will be seen on inspection of Figures 2 and 3. It will be noted that the rings are provided with sloping flanges which insure a rigid and ti ht joint when the sections are secured to ether. The rings 8 and 9 are also provide with oppositely disposed batlie plates 14 and 15 to agitate the. Water as it'passes from one end of the cylinder to the other, and separate-and deposit the solids.

ater is admitted to the c 'linder from the water feed pipe 16 throu an inlet in the head 11, and passes into t e-boiler feed pipe 17 through an outlet in the head 10. The heads are provided with pockets 18 and 19 adjacent the inlet and outlet openings which are arranged to norm'all keep the height f the water somewhat ah ve center line. T he pocket 19 also serves to a itate the incoming Water. feed 16 is provided so that hot water may be supplied to thecylinder from a source other] than the main feed 16. i

Steam from the boiler has access to the interior of the cylinderby 'means of open ings 20 and 21 and is utilized to heat the A ponv or me e-up water and toblow out the mudand scale" which has deposited on the bottom of'the' cylinder. I have provided a number of out-- let openings 22 in t e bottom of the'ciyliir der which are connected to a blow off i-pe 23 leading out ofthe boiler and provided with the usual blow ofi valve, (not shown).

On opening theblow off valve the "liye-stea'm' scale through th'efl pockets 18 and 1:19 i servin as guards to prevent the entrance of blows out the 'mud and discharge pipe 23, the

any 0 the de osit into the water feed 16 and boiler fee 17. 7

The cylinder is suspendedfrmn the ,tie rods 33 by means of a number ofhan ers; (see Figure 3) composed of two mom rs 25 and 26 adapted to embrace the cylinder" and the tie'rods and securedby'nuts 27':

It will be obvious that the hangers are easily" put in place and'aseasilydtach "It is to be noted that by the provisioii of;

the slotted 'l'ings and the sections are securely and rigidly bound, the one to the other, into a firm structure, and are; ntthe same time, readily taken apart for inspection and cleaning. 'The" the through rods 13,

ported upon the rods in the normal steam space of the boiler, joining members for the sections, bafiie plates in the joining members, an inlet from the exterior of the boiler leading into one end of the tank, an outlet leading from the other end of the tank into.

the tank, and a' feed water outlet leading from said pocket.

13.. A feed water heater comprising a horizontal sectional tank means for admitg'live steam to the tank, a blow-out pipe leading from the lower portion of the tank, a. downwardly opening pocket inside one of the heads of thetank, an upwardly opening pocket inside the other head of the tank, a feed water inlet to the downwardly opening pocket, and a feed water outlet from the other pocket.

14. A feed water heater comprising in combination, a body composed of sheet metal sections, joining members between the sections, said joining members being castings provided with integral 'bafile plates and means for securing the joining members together substantially as subscribed.

15. In a boiler, a sectional heater tank in the normal steam space of the boiler and extending longitudinally therein, joining membersin the sections, said joining members being provided with integral bafile plates oppositely disposed one to the other, an inlet leading into one end of the tank from the exterior of the boiler, an outlet leading into the boiler from the other end of the tank, a plurality of pipes leading from different points along the lower portion of the tank and a common blow out pipe connected to such pipes and leading to the exterior of the boiler.

16. A feed water heater comprising in combination, a horizontal tank com osed of sheet metal sections,

live steam to the tank, a blow-out pipe le ,ing from the lower portion of the tank, a downwardly opening pocket inside one of the heads in the tank, a feed water inlet opening into said pocket, and a feed water outlet.

In testimony whereof, I have hereunto si ned my name in the presence of the two SlfiISCllbGd witnesses. 4
